Data::Walk is for data, what File::Find is for file systems. You can
use it for traversing arbitrarily complex Perl data structures.
Its closest relatives on CPAN are currently Data::Traverse and
Data::Walker. Data::Traverse is very similar but can only handle
unblessed references and has less options. Data::Walker offers an
interactive approach for traversing data structures.
Data::Dumper also offers some callbacks when traversing the structures,
but not the ones that I needed. That was motivation enough for writing
Data::Walk.
